SPECIFICATION forming part of Letters Patent No. 551,181, dated December10, 1895.

Application filed April 10, 1895. Serial No. 545,153. (No model.)

T0 at whom, it may concern.-

Be it known that I, JAMES A. DILLON, of Toledo, county of Lucas, andState of Ohio, have invented certain new and useful Improvements inSash-Locks; and I do hereby declare that the following is a full, clear,and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form part of this specification.

My invention relates to a sash-lock, and has for its object to provide asimple and cheap lock which shall be efficient in operation to lockeither sash when closed or partly open.

The invention consists in a casing having a face-plate secured into theupper sash of the window at a point near the joinder of the two sashesof the windows when closed, there being a weighted catch pivoted in thecasing and provided with a plurality of contact-points which shallengage when the sashes are closed with the upper rail of the lower sashand thus prevent the lower sash from raising or the upper sash fromlowering, the enlarged portion of the catch, which is the weight, beinglimited in its outward movement by contact with the face-plate.

The invention further consists in the combination of parts, as will behereinafter more fully described and claimed.

In the drawings, Figure 1 designates an elevation of a portion of awindow-sash, showing my improved sash-lock in operation thereon. Fig. 2is a sectional elevation of a portion of the sash, the lock being shownin section. Fig. 3 is a detail view of the catch, showing moreparticularly the combinedweight and stop.

1 designates the lower sash and 2 the upper sash of a window, the uppersash being recessed, in which is secured a casing 3 by means of screws4. The casing comprises a chamber 5 and a face-plate 5, the frontopening 6 with the contracted front portion of the casing and limits theoutward movement of the catch. The lower forward portion of catch isprovided with a plurality of stops 9, two being shown in the drawings,although Iwish it understood that as many stops may be employed asdesired without departing from the spirit of my invention, the stopsbeing so arranged in relation to each other that when the lower one isout of engagement with the upper rail of the lower sash, due to thecatch being pushed back, the next higher one projects enough to engagetherewith. Therefore to raise the lower sash or to lower the upper sashthe front portion of the catch must be pushed back flush with the frontportion of the casing, there being a buffer 10 which rises against thecasing and prevents scratching or marring of the same.

What I claim is- In a sash look, a face plate having a slot therein, acasing in rear of the face plate having a chamber of slightly greaterwidth than the slot, a catch pivotally secured in the casing of a sizeto pass through the slot in the face plate, said catch having anintegral enlargement which forms a combined weight and stop, normallyabutting against the face plate inside the casing and a plurality ofstops for engagement with the upper rail of the lower sash.

In testimony that I claim the foregoing as my own I hereby affix mysignature in pres ence of two witnesses.
